103
Brett Cannon9adeab72006-09-20 18:34:28 +0000104- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
105 allows calling unicode() on exceptions classes directly to succeed.
106
Georg Brandlec6c2df2006-09-11 09:38:35 +0000107- Make _PyGILState_NoteThreadState() static, it was not used anywhere

125 head is the original string if sep was not found.
126
Neal Norwitzdac090d2006-09-05 03:53:08 +0000127- Bug #1520864: unpacking singleton tuples in list comprehensions and
128 generator expressions (x for x, in ... ) works again. Fixing this problem
129 required changing the .pyc magic number. This means that .pyc files

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000136- Add new requirements for metaclasses. 1) If type or a subclass of type
137 occurs in __bases__, it must occur before any non-type bases, e.g.
138 before regular classes. 2) If you assign to __bases__, you may not
139 change the metaclass. Many more illegal assignments to __bases__
140 are now checked and raise TypeErrors. This changed fixed at least
141 one known crash.

603Core and builtins
604-----------------
605
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000606- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000607 compared equal or unequal to a string and a UnicodeDecodeError
608 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000609
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000610 Instead, the equal (==) and unequal (!=) comparison operators will
611 now issue a UnicodeWarning and interpret the two objects as
612 unequal. The UnicodeWarning can be filtered as desired using
613 the warning framework, e.g. silenced completely, turned into an
614 exception, logged, etc.
615
616 Note that compare operators other than equal and unequal will still
617 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000618
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000619- Fix segfault when doing string formatting on subclasses of long.
620
621- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
622 with new-style classes.
623
624- Fix bug related to __len__ functions returning negative values with
625 classic classes.
626
627- Patch #1538606, Fix __index__() clipping. There were some problems
628 discovered with the API and how integers that didn't fit into Py_ssize_t
629 were handled. This patch attempts to provide enough alternatives
630 to effectively use __index__.
631
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000632- Bug #1536021: __hash__ may now return long int; the final hash
633 value is obtained by invoking hash on the long int.
634
Thomas Hellerab1049c2006-08-08 17:37:00 +0000635- Bug #1536786: buffer comparison could emit a RuntimeWarning.
636
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000637- Bug #1535165: fixed a segfault in input() and raw_input() when
638 sys.stdin is closed.
639
Thomas Heller74d36f02006-08-04 18:17:40 +0000640- On Windows, the PyErr_Warn function is now exported from
641 the Python dll again.
642
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000643- Bug #1191458: tracing over for loops now produces a line event
644 on each iteration. Fixing this problem required changing the .pyc
645 magic number. This means that .pyc files generated before 2.5c1
646 will be regenerated.
647
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000648- Bug #1333982: string/number constants were inappropriately stored
649 in the byte code and co_consts even if they were not used, ie
650 immediately popped off the stack.
651
Georg Brandle9462c72006-08-04 18:03:37 +0000652- Fixed a reference-counting problem in property().
653
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000654
655Library
656-------
657
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000658- Fix a bug in the ``compiler`` package that caused invalid code to be
659 generated for generator expressions.
660
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000661- The distutils version has been changed to 2.5.0. The change to
662 keep it programmatically in sync with the Python version running
663 the code (introduced in 2.5b3) has been reverted. It will continue
664 to be maintained manually as static string literal.
665
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000666- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000667 and this cannot be converted to the required C type, an exception is
668 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000669 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000670
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000671- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000672 an exception.
673
Tim Petersc10c9d02006-09-05 02:18:09 +0000674- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000675 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000676 workarounds for clocks with low resolution, to stop the code yielding
677 duplicate UUIDs.
678
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000679- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
680 before raising SystemExit, allowing IDLE to honor quit() and exit().
681
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000682- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
683
Georg Brandl7a1af772006-08-14 21:55:28 +0000684- Patch #1536071: trace.py should now find the full module name of a
685 file correctly even on Windows.
686
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000687- logging's atexit hook now runs even if the rest of the module has
688 already been cleaned up.
689
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000690- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000691
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000692- Bug #1531405, format_exception no longer raises an exception if
693 str(exception) raised an exception.
694
Neil Schemenauer06ded092006-08-04 16:20:30 +0000695- Fix a bug in the ``compiler`` package that caused invalid code to be
696 generated for nested functions.
697
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000698
699Extension Modules
700-----------------
701
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000702- Patch #1511317: don't crash on invalid hostname (alias) info.
703
Georg Brandl3335a7a2006-08-14 21:42:55 +0000704- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
705 raises the correct exceptions.
706
Thomas Heller1ce433e2006-08-14 16:20:04 +0000707- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
708 '-no-stack-protector' compiler flag for OpenBSD has been removed.
709
Thomas Heller86720042006-08-14 11:17:48 +0000710- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
711 uses the _as_parameter_ attribute when objects are passed to foreign
712 function calls. The ctypes version number was changed to 1.0.1.
713
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000714- Bug #1530559, struct.pack raises TypeError where it used to convert.
715 Passing float arguments to struct.pack when integers are expected
716 now triggers a DeprecationWarning.
717
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000718
719Tests
720-----
721
Neal Norwitzb476fdf2006-08-15 04:58:28 +0000722- test_socketserver should now work on cygwin and not fail sporadically
723 on other platforms.

728
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000729- test_threading now skips testing alternate thread stack sizes on
730 platforms that don't support changing thread stack size.
731
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000732
Georg Brandl212b5872006-08-05 06:10:54 +0000733Documentation
734-------------
735
736- Patch #1534922: unittest docs were corrected and enhanced.
737
738
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000739Build
740-----
741
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000742- Bug #1535502, build _hashlib on Windows, and use masm assembler
743 code in OpenSSL.
744
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000745- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000749
Tim Peters4643c2f2006-08-10 22:45:34 +0000750C API
751-----
752
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000753- New API for Unicode rich comparisons: PyUnicode_RichCompare()
754
Tim Peters4643c2f2006-08-10 22:45:34 +0000755- Bug #1069160. Internal correctness changes were made to
756 ``PyThreadState_SetAsyncExc()``. A test case was added, and
757 the documentation was changed to state that the return value
758 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000761What's New in Python 2.5 beta 3?
762================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000763
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000764*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000765
766Core and builtins
767-----------------
768
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000769- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000770 returned a long (see PEP 353).
771
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000772- Bug #1515471: string.replace() accepts character buffers again.
773
Neal Norwitz07aadb12006-07-30 06:55:48 +0000774- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
775 This provides the proper warning for struct.pack().
776 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
777
Neal Norwitz0d62a062006-07-30 06:53:31 +0000778- Patch #1531113: Fix augmented assignment with yield expressions.
779 Also fix a SystemError when trying to assign to yield expressions.
780
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000781- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
782 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
783 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
784 excessive filesystem operations during imports.
785
Tim Petersbc24eee2006-07-27 01:14:53 +0000786- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
787 operations on signed longs that are formally undefined by C.
788 Unfortunately, at least one compiler now cares about that, so complicated
789 the code to make that compiler happy again.
790
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000791- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
792
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000793- Patch #1232023: Stop including current directory in search
794 path on Windows.
795
Neal Norwitze1fdb322006-07-21 05:32:28 +0000796- Fix some potential crashes found with failmalloc.
797
Neal Norwitze7563102006-07-17 01:00:16 +0000798- Fix warnings reported by Klocwork's static analysis tool.
799
Neal Norwitz84be93b2006-07-16 01:50:38 +0000800- Bug #1512814, Fix incorrect lineno's when code within a function
801 had more than 255 blank lines.
802
Georg Brandl9dceedb2006-07-12 15:31:17 +0000803- Patch #1521179: Python now accepts the standard options ``--help`` and
804 ``--version`` as well as ``/?`` on Windows.
805
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000806- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000807 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000808 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000809
Tim Peters112aad32006-07-19 00:03:19 +0000810- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000811 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000812 new ``sys._current_frames()`` returns a dictionary with one entry,
813 mapping the faux "thread id" 0 to the current frame.
814
Ronald Oussoren3075e162006-07-25 20:28:55 +0000815- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000816
Ronald Oussoren3075e162006-07-25 20:28:55 +0000817
Neal Norwitza1f10902006-07-12 07:28:29 +0000818Library
819-------
820
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000821- Correction of patch #1455898: In the mbcs decoder, set final=False
822 for stream decoder, but final=True for the decode function.
823
Georg Brandl07fec3a2006-08-01 18:49:24 +0000824- os.urandom no longer masks unrelated exceptions like SystemExit or
825 KeyboardInterrupt.
826
Tim Peters4643c2f2006-08-10 22:45:34 +0000827- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000828 shutil.copytree on Windows
829
Georg Brandle34ac7c2006-07-30 11:07:23 +0000830- Bug #1002398: The documentation for os.path.sameopenfile now correctly
831 refers to file descriptors, not file objects.
832
Tim Petersc10c9d02006-09-05 02:18:09 +0000833- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000834 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000835 #1513611, and probably others.
836
Georg Brandledd9b0d2006-07-29 09:33:26 +0000837- Bug #1441397: The compiler module now recognizes module and function
838 docstrings correctly as it did in Python 2.4.
839
Tim Peters6f681472006-07-27 23:44:37 +0000840- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
841 lost that tests are sorted by name before being run. This rarely
842 matters for well-written tests, but can create baffling symptoms if
843 side effects from one test to the next affect outcomes. ``DocTestFinder``
844 has been changed to sort the list of tests it returns.
845
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000846- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000847 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000848
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000849- Bug #978833: Really close underlying socket in _socketobject.close.
850
Georg Brandl8c036cc2006-08-20 13:15:39 +0000851- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
852 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000853
Georg Brandlcf0c1722006-07-26 07:23:32 +0000854- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
855 to recursive calls and call it with the failing package name.
856
Martin v. Löwis0b483032006-07-25 09:53:12 +0000857- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
858
Georg Brandlc13c34c2006-07-24 14:09:56 +0000859- Patch #1515343: Fix printing of deprecated string exceptions with a
860 value in the traceback module.
861
Greg Ward48fae7a2006-07-23 16:05:51 +0000862- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
863
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000864- Patch #1524429: Use repr() instead of backticks in Tkinter again.
865
Brett Cannoncaebe222006-07-18 04:41:36 +0000866- Bug #1520914: Change time.strftime() to accept a zero for any position in its
867 argument tuple. For arguments where zero is illegal, the value is forced to
868 the minimum value that is correct. This is to support an undocumented but
869 common way people used to fill in inconsequential information in the time
870 tuple pre-2.4.
871
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000872- Patch #1220874: Update the binhex module for Mach-O.
873
Barry Warsawb110bad2006-07-21 14:51:07 +0000874- The email package has improved RFC 2231 support, specifically for
875 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
876 (name*0=<blah>) parameter continuations. This may change the types of
877 values returned from email.message.Message.get_param() and friends.
878 Specifically in some cases where non-encoded continuations were used,
879 get_param() used to return a 3-tuple of (None, None, string) whereas now it
880 will just return the string (since non-encoded continuations don't have
881 charset and language parts).
882
883 Also, whereas % values were decoded in all parameter continuations, they are
884 now only decoded in encoded parameter parts.
885
Ronald Oussoren3075e162006-07-25 20:28:55 +0000886- Bug #1517990: IDLE keybindings on MacOS X now work correctly
887
888- Bug #1517996: IDLE now longer shows the default Tk menu when a
889 path browser, class browser or debugger is the frontmost window on MacOS X

Barry Warsaw00decd72006-07-27 23:43:15 +0000891- Patch #1520294: Support for getset and member descriptors in types.py,
892 inspect.py, and pydoc.py. Specifically, this allows for querying the type
893 of an object against these built-in types and more importantly, for getting
894 their docstrings printed in the interactive interpreter's help() function.

898-----------------
899
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000900- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
901 a socket operation on a socket with a timeout, the exception will be
902 caught correctly. Previously, the exception was not caught.
903
Thomas Heller1393d6a2006-07-28 21:43:20 +0000904- Patch #1529514: The _ctypes extension is now compiled on more
905 openbsd target platforms.
906
Tim Peters9cab5932006-07-28 00:30:00 +0000907- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
908 a memory leak, affecting pickles and deep copies.
909
Tim Petersbc24eee2006-07-27 01:14:53 +0000910- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

914
Thomas Hellerce049a02006-07-14 17:51:14 +0000915- Patch #1521817: Index range checking on ctypes arrays containing
916 exactly one element enabled again. This allows iterating over these
917 arrays, without the need to check the array size before.
918
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000919- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000920 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000921 /dev/null in certain cases; this is now fixed.
922
Thomas Heller47d7a062006-07-12 08:43:47 +0000923- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
924 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000925
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000926- Because of a misspelled preprocessor symbol, ctypes was always
927 compiled without thread support; this is now fixed.
928
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000929- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
930 methods now allow their database parameter to be None as the
931 sleepycat API allows.
932
Matt Flemingec926502006-07-28 11:27:27 +0000933- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
934 bluetooth API compared with Linux and FreeBSD.
935
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000936Tests
937-----
938
939- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
940 how long the test file should take to play. Now accepts taking 2.93 secs
941 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
942
Georg Brandl4793aa32006-07-28 18:31:39 +0000943- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
944 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
945 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000946
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000947Build
948-----
949
950- Bug #1439538: Drop usage of test -e in configure as it is not portable.
951
Ronald Oussoren26cad082006-08-01 21:00:57 +0000952Mac
953---
954
955- PythonLauncher now works correctly when the path to the script contains
956 characters that are treated specially by the shell (such as quotes).
957
958- Bug #1527397: PythonLauncher now launches scripts with the working directory
959 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000960 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000961 expect.

969Core and builtins
970-----------------
971
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000972- Bug #1441486: The literal representation of -(sys.maxint - 1)
973 again evaluates to a int object, not a long.
974
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000975- Bug #1501934: The scope of global variables that are locally assigned
976 using augmented assignment is now correctly determined.
977
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000978- Bug #927248: Recursive method-wrapper objects can now safely
979 be released.
980
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000981- Bug #1417699: Reject locale-specific decimal point in float()
982 and atof().
983
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000984- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
985 omit a default "error" argument for NULL pointer. This allows
986 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000987
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000988- Bug #1519018: 'as' is now validated properly in import statements.
989
Neal Norwitz28746ab2006-07-09 22:14:42 +0000990- On 64 bit systems, int literals that use less than 64 bits are
991 now ints rather than longs.
992
Neal Norwitzed657552006-07-10 00:04:44 +0000993- Bug #1512814, Fix incorrect lineno's when code at module scope
994 started after line 256.
995
Tim Peters32a83612006-07-10 21:08:24 +0000996- New function ``sys._current_frames()`` returns a dict mapping thread
997 id to topmost thread stack frame. This is for expert use, and is
998 especially useful for debugging application deadlocks. The functionality
999 was previously available in Fazal Majid's ``threadframe`` extension
1000 module, but it wasn't possible to do this in a wholly threadsafe way from
1001 an extension.
1002

1010
Tim Peters32a83612006-07-10 21:08:24 +00001011- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001012 environment variable to be set in order to the SDK environment
1013 for finding the compiler, include files, etc.

1018
Thomas Woutersadd19112006-07-05 11:03:49 +00001019- string.Template() now correctly handles tuple-values. Previously,
1020 multi-value tuples would raise an exception and single-value tuples would
1021 be treated as the value they contain, instead.
1022
Martin v. Löwisede77f52006-07-03 13:01:35 +00001023- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1024 even if some data are received.
1025
Martin v. Löwis45482392006-07-03 12:28:58 +00001026- Bug #1267547: Put proper recursive setup.py call into the
1027 spec file generated by bdist_rpm.
1028
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001029- Bug #1514693: Update turtle's heading when switching between
1030 degrees and radians.
1031
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001032- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001033 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001034
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001035- Bug #1514703: Only setup canvas window in turtle when the canvas
1036 is created.
1037
Martin v. Löwis7596e832006-07-01 15:33:37 +00001038- Bug #1513223: .close() of a _socketobj now releases the underlying

1042 attribute values.
1043
1044- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1045 sgmllib ('[' and ']' were not accepted).
1046
Georg Brandl1be63af2006-06-28 20:23:25 +00001047- Fix a bug in the turtle module's end_fill function.
1048
Brett Cannon53ab5b72006-06-22 16:49:14 +00001049- Bug #1510580: The 'warnings' module improperly required that a Warning
1050 category be either a types.ClassType and a subclass of Warning. The proper
1051 check is just that it is a subclass with Warning as the documentation states.
1052
Georg Brandlad29e632006-06-21 17:45:17 +00001053- The compiler module now correctly compiles the new try-except-finally
1054 statement (bug #1509132).
1055
Neal Norwitz60373cd2006-06-22 06:30:50 +00001056- The wsgiref package is now installed properly on Unix.
1057
Vinay Sajip28e57612006-07-01 10:45:20 +00001058- A bug was fixed in logging.config.fileConfig() which caused a crash on
1059 shutdown when fileConfig() was called multiple times.
1060
Gerhard Häring762fbd32006-07-02 17:48:30 +00001061- The sqlite3 module did cut off data from the SQLite database at the first
1062 null character before sending it to a custom converter. This has been fixed
1063 now.
1064
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001065Extension Modules
1066-----------------
1067
Tim Peters112aad32006-07-19 00:03:19 +00001068- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1069 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1070 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001071
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001072- Assigning None to pointer type fields in ctypes structures possible
1073 overwrote the wrong fields, this is fixed now.
1074
1075- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1076 on non-Windows platforms.
1077
1078- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1079 integer or long, without range checking.
1080
1081- Patch #1517790: It is now possible to use custom objects in the ctypes
1082 foreign function argtypes sequence as long as they provide a from_param
1083 method, no longer is it required that the object is a ctypes type.
1084
1085- The '_ctypes' extension module now works when Python is configured
1086 with the --without-threads option.
1087
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001088- Bug #1513646: os.access on Windows now correctly determines write
1089 access, again.
1090
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001091- Bug #1512695: cPickle.loads could crash if it was interrupted with
1092 a KeyboardInterrupt.
1093
Neal Norwitza12aa882006-07-06 06:45:08 +00001094- Bug #1296433: parsing XML with a non-default encoding and
1095 a CharacterDataHandler could crash the interpreter in pyexpat.
1096
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001097- Patch #1516912: improve Modules support for OpenVMS.
1098
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001099Build
1100-----
1101
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001102- Automate Windows build process for the Win64 SSL module.
1103
Tim Peters32a83612006-07-10 21:08:24 +00001104- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001105 Previously, the slight difference could cause compilation errors of the
1106 'zlib' module on systems with more than one version of zlib.
1107
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001108- The MSI compileall step was fixed to also support a TARGETDIR
1109 with spaces in it.
1110
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001111- Bug #1517388: sqlite3.dll is now installed on Windows independent
1112 of Tcl/Tk.
1113
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001114- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001115 trying to be installed even though it's empty.

1124-------------
1125
Nick Coghlan2d792252006-07-06 13:47:18 +00001126- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1127 documentation for the warnings module.
1128
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001129- Patch #1509163: MS Toolkit Compiler no longer available.
1130

1140-----------------
1141
Georg Brandla56b9152006-06-19 06:35:54 +00001142- Patch #1507676: Error messages returned by invalid abstract object operations
1143 (such as iterating over an integer) have been improved and now include the
1144 type of the offending object to help with debugging.
1145
Brett Cannonea3912b2006-06-13 21:46:41 +00001146- Bug #992017: A classic class that defined a __coerce__() method that returned
1147 its arguments swapped would infinitely recurse and segfault the interpreter.
1148
Neal Norwitz909eb122006-06-12 02:13:21 +00001149- Fix the socket tests so they can be run concurrently.
1150
Neal Norwitzb9845e72006-06-12 02:11:18 +00001151- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001152 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001153
Brett Cannon22565aa2006-06-09 22:31:23 +00001154- Bug #532646: object.__call__() will continue looking for the __call__
1155 attribute on objects until one without one is found. This leads to recursion
1156 when you take a class and set its __call__ attribute to an instance of the
1157 class. Originally fixed for classic classes, but this fix is for new-style.
1158 Removes the infinite_rec_3 crasher.
1159
Georg Brandl24250812006-06-09 18:45:48 +00001160- The string and unicode methods startswith() and endswith() now accept
1161 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1162
Brett Cannonde3b0522006-06-08 17:00:45 +00001163- Buffer objects, at the C level, never used the char buffer
1164 implementation even when the char buffer for the wrapped object was
1165 explicitly requested (originally returned the read or write buffer).
1166 Now a TypeError is raised if the char buffer is not present but is
1167 requested.
1168
Georg Brandlddbaa662006-06-04 21:56:52 +00001169- Patch #1346214: Statements like "if 0: suite" are now again optimized
1170 away like they were in Python 2.4.
1171
Georg Brandlb7c8f542006-05-27 12:30:25 +00001172- Builtin exceptions are now full-blown new-style classes instead of
1173 instances pretending to be classes, which speeds up exception handling
1174 by about 80% in comparison to 2.5a2.
1175
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001176- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1177 Unicode 4.1.
1178
Georg Brandlf4ef1162006-05-26 18:03:31 +00001179- Patch #921466: sys.path_importer_cache is now used to cache valid and
1180 invalid file paths for the built-in import machinery which leads to
1181 fewer open calls on startup.
1182
Tim Peters696cf432006-05-24 21:10:40 +00001183- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1184 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1185 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1186 the number of input digits (it was and remains linear-time for bases
1187 2, 4, 8, 16 and 32).
1188
Tim Petersb713ec22006-05-23 18:45:30 +00001189- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1190 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1191 an integer close to ``sys.maxint``. This was repaired by patch
1192 #1335972, which also gives a nice speedup.
1193
Richard Jonescebbefc2006-05-23 18:28:17 +00001194- Patch #1337051: reduced size of frame objects.
1195
1196- PyErr_NewException now accepts a tuple of base classes as its
1197 "base" parameter.
1198
Richard Jones7c88dcc2006-05-23 10:37:38 +00001199- Patch #876206: function call speedup by retaining allocated frame
1200 objects.
1201
Georg Brandl7b90e162006-05-18 07:01:27 +00001202- Bug #1462152: file() now checks more thoroughly for invalid mode
1203 strings and removes a possible "U" before passing the mode to the
1204 C library function.
1205
Neal Norwitz1004a532006-05-15 07:17:23 +00001206- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1207
Neal Norwitz373f0a72006-05-15 07:04:36 +00001208- Bug #1487966: Fix SystemError with conditional expression in assignment
1209
Martin v. Löwis879768d2006-05-11 13:28:43 +00001210- WindowsError now has two error code attributes: errno, which carries
1211 the error values from errno.h, and winerror, which carries the error
1212 values from winerror.h. Previous versions put the winerror.h values
1213 (from GetLastError()) into the errno attribute.
1214
Martin v. Löwis77736712006-05-04 05:51:03 +00001215- Patch #1475845: Raise IndentationError for unexpected indent.
1216
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001217- Patch #1479181: split open() and file() from being aliases for each other.
1218
Tim Peters44bd9862006-06-01 13:49:23 +00001219- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1220 methods were always silently ignored by dictionaries when comparing keys.
1221 They are now passed through (except when using the C API function
1222 ``PyDict_GetItem()``, whose semantics did not change).
1223
1224- Bug #1456209: In some obscure cases it was possible for a class with a
1225 custom ``__eq__()`` method to confuse dict internals when class instances
1226 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1227 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001229Extension Modules
1230-----------------
1231
Trent Mick960a3f82006-06-28 20:30:41 +00001232- Bug #1295808: expat symbols should be namespaced in pyexpat
1233
1234- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1235
Brett Cannon6ee7d012006-06-08 16:23:04 +00001236- Change binascii.hexlify to accept a read-only buffer instead of only a char
1237 buffer and actually follow its documentation.
1238
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001239- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1240
Nick Coghlanc649ec52006-05-29 12:43:05 +00001241- Patch #1478788 (modified version): The functional extension module has
1242 been renamed to _functools and a functools Python wrapper module added.
1243 This provides a home for additional function related utilities that are
1244 not specifically about functional programming. See PEP 309.
1245
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001246- Patch #1493701: performance enhancements for struct module.
1247
Georg Brandl378d5922006-05-17 14:26:50 +00001248- Patch #1490224: time.altzone is now set correctly on Cygwin.
1249
Georg Brandl8d3342b2006-05-16 07:38:27 +00001250- Patch #1435422: zlib's compress and decompress objects now have a
1251 copy() method.
1252
Andrew MacIntyre92913322006-06-13 15:04:24 +00001253- Patch #1454481: thread stack size is now tunable at runtime for thread
1254 enabled builds on Windows and systems with Posix threads support.
1255
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001256- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1257 (up to the system limit of 32K characters).
1258
1259- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1260 As a result, these functions now raise WindowsError instead of OSError.
1261
Tim Peters7a822da2006-05-25 21:50:17 +00001262- ``time.clock()`` on Win64 should use the high-performance Windows
1263 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1264 Windows platforms).
1265
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001266- Calling Tk_Init twice is refused if the first call failed as that
1267 may deadlock.
1268
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001269- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1270 accept it without potentially using an uninitialized pointer.
1271
1272- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1273 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1274 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001275
Gregory P. Smith372b5832006-06-05 18:48:21 +00001276- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001277 [pybsddb project SF patch number 1466734]
1278
Gregory P. Smith372b5832006-06-05 18:48:21 +00001279- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1280 parameter is supplied. [SF pybsddb bug #1477863]
1281
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001282- bsddb: the __len__ method of a DB object has been fixed to return correct
1283 results. It could previously incorrectly return 0 in some cases.
1284 Fixes SF bug 1493322 (pybsddb bug 1184012).
1285
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001286- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1287 aborts the db transaction safely when a modifier callback fails.
1288 Fixes SF python patch/bug #1408584.
1289
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001290- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001291 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001292 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1293 database calls that would previously deadlock. [SF python bug #775414]
1294
Vinay Sajip28e57612006-07-01 10:45:20 +00001295- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001296
Walter Dörwald4994d952006-06-19 08:07:50 +00001297- Patch #1506645: add Python wrappers for the curses functions
1298 is_term_resized, resize_term and resizeterm.

1302
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001303- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1304 functions.
1305
Martin v. Löwis3798da02006-06-17 18:44:27 +00001306- Patch #812986: Update turtle output even if not tracing.
1307
Vinay Sajip28e57612006-07-01 10:45:20 +00001308- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001309 Tkinter.BaseWidget.
1310
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001311- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1312
Martin v. Löwis337487e2006-06-17 09:15:14 +00001313- Patch #763580: Add name and value arguments to Tkinter variable
1314 classes.
1315
Georg Brandl83cc0d02006-06-14 08:50:03 +00001316- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1317 mime.types file for determining MIME types.
1318
Georg Brandl2605ca82006-06-14 06:08:31 +00001319- Bug #1339007: Shelf objects now don't raise an exception in their
1320 __del__ method when initialization failed.
1321
Martin v. Löwisd8251432006-06-14 05:21:04 +00001322- Patch #1455898: The MBCS codec now supports the incremental mode for
1323 double-byte encodings.
1324
Tim Peters43898b42006-06-14 04:09:25 +00001325- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1326 guarantee that adjacent triples in the return list always describe
1327 non-adjacent blocks. Previously, a pair of matching blocks could end
1328 up being described by multiple adjacent triples that formed a partition
1329 of the matching pair.
1330
Greg Ward0e0c9f42006-06-11 16:24:11 +00001331- Bug #1498146: fix optparse to handle Unicode strings in option help,
1332 description, and epilog.
1333
Greg Wardd1c797e2006-06-11 14:42:41 +00001334- Bug #1366250: minor optparse documentation error.
1335
Greg Ward7f547402006-06-11 00:40:49 +00001336- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1337 clarify docs.
1338
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001339- The wsgiref package has been added to the standard library.
1340
Nick Coghlan676725d2006-06-08 13:54:49 +00001341- The functions update_wrapper() and wraps() have been added to the functools
1342 module. These make it easier to copy relevant metadata from the original
1343 function when writing wrapper functions.
1344
Tim Petersd6a9eef2006-06-05 01:48:21 +00001345- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1346 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001347
Martin v. Löwis3f767792006-06-04 19:36:28 +00001348- Patch #1359618: Speed up charmap encoder by using a trie structure
1349 for lookup.
1350
Tim Petersd609b1a2006-06-02 23:22:51 +00001351- The functions in the ``pprint`` module now sort dictionaries by key
1352 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1353 if and only if its display required more than one line, although that
1354 wasn't documented. The new behavior increases predictability; e.g.,
1355 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1356
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001357- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1358 (thanks for J. J. Lee).
1359
Georg Brandl2b330372006-05-28 20:23:12 +00001360- Patch #1496206: improve urllib2 handling of passwords with respect to
1361 default HTTP and HTTPS ports.
1362
George Yoshidaf3c65de2006-05-28 16:39:09 +00001363- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1364
Bob Ippolito7298f272006-05-23 18:43:47 +00001365- Patch #1281707: speed up gzip.readline.
1366
Georg Brandlb89316f2006-05-17 15:51:16 +00001367- Patch #1180296: Two new functions were added to the locale module:
1368 format_string() to get the effect of "format % items" but locale-aware,
1369 and currency() to format a monetary number with currency sign.
1370
Georg Brandle3a25832006-05-17 14:56:04 +00001371- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1372 and several features added, such as speed and geometry control.
1373
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001374- Patch #1488881: add support for external file objects in bz2 compressed
1375 tarfiles.
1376
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001377- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1378 stdout arguments, making it possible to redirect input and output
1379 for remote debugging.
1380
1381- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1382 a couple of issues, notably handling of long file names using the
1383 GNU LONGNAME extension.
1384
1385- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1386 new flag when ``name`` is already the name of an option flag.
1387
1388- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1389 package.
1390
1391- Patch #1472854: make the rlcompleter.Completer class usable on non-
1392 UNIX platforms.
1393
1394- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1395
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001396- Bug #1472827: correctly escape newlines and tabs in attribute values in
1397 the saxutils.XMLGenerator class.

1429
1430*Release date: 27-APR-2006*
1431
1432Core and builtins
1433-----------------
1434
Thomas Heller1b046642006-04-18 18:51:06 +00001435- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1436 by converting these apis from macros into exported functions again:
1437
1438 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1439 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1440 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1441 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1442 PyRun_String Py_CompileString
1443
Martin v. Löwis45294a92006-04-18 06:24:08 +00001444- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1445
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001446- All uses of PyStructSequence_InitType have been changed to initialize
1447 the type objects only once, even if the interpreter is initialized
1448 multiple times.
1449
Neal Norwitz61546162006-04-14 05:20:28 +00001450- Bug #1454485, array.array('u') could crash the interpreter. This was
1451 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1452 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1453
1454- Py_UNICODE is unsigned. It was always documented as unsigned, but
1455 due to a bug had a signed value in previous versions.
1456
Tim Peters3a5e8b12006-04-11 01:44:07 +00001457- Patch #837242: ``id()`` of any Python object always gives a positive
1458 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1459 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001460 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001461 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001462
Tim Peters3a5e8b12006-04-11 01:44:07 +00001463 def __hash__(self):
1464 return id(self) # WRONG
1465
1466 because a hash result must be a (short) Python int but it was always
1467 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001468 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001469 was always usable as a hash value before this patch. That's no longer
1470 necessarily so.
1471
1472- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001473 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001474 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001475 #1454844)
1476
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001477- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1478 involving generators that have paused outside of any ``try`` or ``with``
1479 blocks. (In 2.5a1, a paused generator that was part of a reference
1480 cycle could not be garbage collected, regardless of whether it was
1481 paused in a ``try`` or ``with`` block.)

1484-----------------
1485
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001486- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1487 is a macro.
1488
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001489- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1490 fails with an error condition.
1491
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001492- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1493
1494- Bug #1117761: bsddb.*open() no longer raises an exception when using
1495 the cachesize parameter.
1496
1497- Bug #1149413: bsddb.*open() no longer raises an exception when using
1498 a temporary db (file=None) with the 'n' flag to truncate on open.
1499
1500- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1501 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001502
Armin Rigoa9017c32006-04-19 11:50:27 +00001503- Patch #1062014: AF_UNIX sockets under Linux have a special
1504 abstract namespace that is now fully supported.

1508
Peter Astrand7d1d4362006-07-14 14:04:45 +00001509- Bug #1223937: subprocess.CalledProcessError reports the exit status
1510 of the process using the returncode attribute, instead of
1511 abusing errno.
1512
Tim Peters711bf302006-04-25 03:31:36 +00001513- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1514 a doctest to be skipped (the code is not run, and the expected output
1515 or exception is ignored).
1516
Nick Coghlanda2268f2006-04-24 04:37:15 +00001517- Fixed contextlib.nested to cope with exceptions being raised and
1518 caught inside exit handlers.
1519
Greg Wardab05edc2006-04-23 03:47:58 +00001520- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1521 hex, octal, or binary; add ``append_const`` action; keep going if
1522 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1523 added ``epilog`` for better help generation).
1524
Tim Peters21fbd572006-04-21 21:18:10 +00001525- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1526 called from a thread spawned as a side effect of importing a module.
1527
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001528- The pydoc module now supports documenting packages contained in
1529 .zip or .egg files.
1530
1531- The pkgutil module now has several new utility functions, such
1532 as ``walk_packages()`` to support working with packages that are either
1533 in the filesystem or zip files.
1534
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001535- The mailbox module can now modify and delete messages from
1536 mailboxes, in addition to simply reading them. Thanks to Gregory
1537 K. Johnson for writing the code, and to the 2005 Google Summer of
1538 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001539
Tim Petersc7605f22006-04-17 21:12:33 +00001540- The ``__del__`` method of class ``local`` in module ``_threading_local``
1541 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +00001549- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1550 Windows. Bug #1469163.
1551
Phillip J. Eby47032112006-04-11 01:07:43 +00001552- The warnings, linecache, inspect, traceback, site, and doctest modules
1553 were updated to work correctly with modules imported from zipfiles or
1554 via other PEP 302 __loader__ objects.
1555
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001556- Patch #1467770: Reduce usage of subprocess._active to processes which
1557 the application hasn't waited on.

1562
Skip Montanaro262fb922006-04-21 02:31:07 +00001563- The pstats.Stats class accepts an optional stream keyword argument to
1564 direct output to an alternate file-like object.
1565
Anthony Baxter51bcb682006-04-05 14:51:42 +00001566Build
1567-----
1568
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001569- The Makefile now has a reindent target, which runs reindent.py on
1570 the library.
1571
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001572- Patch #1470875: Building Python with MS Free Compiler
1573

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001575
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001576- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1577 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001578 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001579 CXX from --with-cxx-main, see description in README.
1580
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001581- Patch #1429775: Link extension modules with the shared libpython.
1582
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001583- Fixed a libffi build problem on MIPS systems.
1584
Tim Peters8931ff12006-05-13 23:28:20 +00001585- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1586 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1587 and "%zu" for unsigned integers of type ``size_t``.
1588
Anthony Baxter51bcb682006-04-05 14:51:42 +00001589Tests
1590-----
1591
Nick Coghlanda2268f2006-04-24 04:37:15 +00001592- test_contextlib now checks contextlib.nested can cope with exceptions
1593 being raised and caught inside exit handlers.
1594
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001595- test_cmd_line now checks operation of the -m and -c command switches
1596
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001597- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1598 it separately and by hand. It also wasn't cleaning up its changes to
1599 the current Decimal context.
1600
Thomas Woutersabd08882006-04-26 15:53:30 +00001601- regrtest.py now has a -M option to run tests that test the new limits of
1602 containers, on 64-bit architectures. Running these tests is only sensible
1603 on 64-bit machines with more than two gigabytes of memory. The argument
1604 passed is the maximum amount of memory for the tests to use.

1613-------------
1614
Tim Petersb06d28c2006-05-12 01:57:59 +00001615- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1616
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001617- PEP 343: Added Context Types section to the library reference
1618 and attempted to bring other PEP 343 related documentation into
1619 line with the implementation and/or python-dev discussions.
1620
Tim Peters8dc73d22006-04-24 02:03:16 +00001621- Bug #1337990: clarified that ``doctest`` does not support examples
1622 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001625What's New in Python 2.5 alpha 1?
1626=================================
1627
Anthony Baxterebed3f62006-04-03 15:03:44 +00001628*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001629
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001630Core and builtins
1631-----------------
1632
Nick Coghlan43832302006-04-23 17:04:07 +00001633- PEP 338: -m command line switch now delegates to runpy.run_module
1634 allowing it to support modules in packages and zipfiles
1635
Martin v. Löwisc661b882006-04-20 04:54:23 +00001636- On Windows, .DLL is not an accepted file name extension for
1637 extension modules anymore; extensions are only found if they
1638 end in .PYD.
1639
Martin v. Löwisea62d252006-04-03 10:56:49 +00001640- Bug #1421664: sys.stderr.encoding is now set to the same value as
1641 sys.stdout.encoding.
1642
Neal Norwitz92e212f2006-04-03 04:48:37 +00001643- __import__ accepts keyword arguments.
1644
Georg Brandlccadf842006-03-31 18:54:53 +00001645- Patch #1460496: round() now accepts keyword arguments.
1646
Anthony Baxter262c00a2006-03-30 10:53:17 +00001647- Fixed bug #1459029 - unicode reprs were double-escaped.
1648
Hye-Shik Changd478f342006-03-23 12:32:36 +00001649- Patch #1396919: The system scope threads are reenabled on FreeBSD
1650 5.4 and later versions.
1651
Neal Norwitze98ccf62006-03-23 05:39:47 +00001652- Bug #1115379: Compiling a Unicode string with an encoding declaration
1653 now gives a SyntaxError.
1654
Georg Brandlabd1ff82006-03-18 07:59:59 +00001655- Previously, Python code had no easy way to access the contents of a
1656 cell object. Now, a ``cell_contents`` attribute has been added
1657 (closes patch #1170323).
1658
Tim Peterscf79aac2006-03-16 01:14:46 +00001659- Patch #1123430: Python's small-object allocator now returns an arena to
1660 the system ``free()`` when all memory within an arena becomes unused
1661 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1662 freed. Some applications will see a drop in virtual memory size now,
1663 especially long-running applications that, from time to time, temporarily
1664 use a large number of small objects. Note that when Python returns an
1665 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001666 platform C library will in turn return that memory to the operating system.
1667 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001668 appears to be effective at least on Microsoft C and gcc-based systems.
1669 Thanks to Evan Jones for hard work and patience.
1670
Georg Brandl533ff6f2006-03-08 18:09:27 +00001671- Patch #1434038: property() now uses the getter's docstring if there is
1672 no "doc" argument given. This makes it possible to legitimately use
1673 property() as a decorator to produce a read-only property.
1674
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001675- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1676 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1677 of requiring an int or long in slicing and a few other contexts, enabling
1678 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1679
Neal Norwitz995acdf2006-03-07 05:01:00 +00001680- Fixed various bugs reported by Coverity's Prevent tool.
1681
Brett Cannonbf364092006-03-01 04:25:17 +00001682- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1683 new exception base class, BaseException, which has a new message attribute.
1684 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1685 Raising a string exception now raises a DeprecationWarning.
1686
Thomas Woutersfb609f42006-02-28 16:37:25 +00001687- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1688 explicitly relative, using 'from .module import name' to mean 'from the same
1689 package as this module is in. Imports without dots still default to the
1690 old relative-then-absolute, unless 'from __future__ import
1691 absolute_import' is used.
1692
Brett Cannona7446e32006-02-27 23:39:10 +00001693- Properly check if 'warnings' raises an exception (usually when a filter set
1694 to "error" is triggered) when raising a warning for raising string
1695 exceptions.
1696
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001697- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001698 The name was removed from Include/code.h.
1699
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001700- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001701
Guido van Rossum1968ad32006-02-25 22:38:04 +00001702- Patch 1433928:
1703 - The copy module now "copies" function objects (as atomic objects).
1704 - dict.__getitem__ now looks for a __missing__ hook before raising
1705 KeyError.
1706
Tim Peters84ef21c2006-02-28 20:39:06 +00001707- PEP 343: with statement implemented. Needs ``from __future__ import
1708 with_statement``. Use of 'with' as a variable will generate a warning.
1709 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001710 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001711 The following objects have __context__ methods:
1712 - The built-in file type.
1713 - The thread.LockType type.
1714 - The following types defined by the threading module:
1715 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1716 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001717
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001718- Fix the encodings package codec search function to only search
1719 inside its own package. Fixes problem reported in patch #1433198.
1720
1721 Note: Codec packages should implement and register their own
1722 codec search function. PEP 100 has the details.
1723
Tim Peters9ea89d22006-06-04 03:26:02 +00001724- PEP 353: Using ``Py_ssize_t`` as the index type.
1725
1726- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1727 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1728 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1729 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1730 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001731
Neal Norwitzfc76d632006-01-10 06:03:13 +00001732- Patch #1400181, fix unicode string formatting to not use the locale.
1733 This is how string objects work. u'%f' could use , instead of .
1734 for the decimal point. Now both strings and unicode always use periods.
1735
Neal Norwitz671b9e32006-01-09 07:07:12 +00001736- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1737 configure would break checking curses.h.
1738
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001739- Bug #959576: The pwd module is now builtin. This allows Python to be
1740 built on UNIX platforms without $HOME set.
1741
Neal Norwitzc10978f2005-12-19 06:07:16 +00001742- Bug #1072182, fix some potential problems if characters are signed.
1743
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001744- Bug #889500, fix line number on SyntaxWarning for global declarations.
1745
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001746- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1747
Neal Norwitze7214a12005-12-18 05:03:17 +00001748- Support for converting hex strings to floats no longer works.
1749 This was not portable. float('0x3') now raises a ValueError.
1750
Barry Warsaw2a38a862005-12-18 01:27:35 +00001751- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001752 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001753 is now displayed in interactive prompt banner.
1754
Georg Brandlfa166682005-12-17 21:45:17 +00001755- Implementation of PEP 341 - Unification of try/except and try/finally.
1756 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001757 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001758
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001759- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1760 now encodes backslash correctly.
1761
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001762- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1763
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001764- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001765 and long longs.
1766
Neal Norwitz67715f02005-11-09 06:59:35 +00001767- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001768 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001769 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001770
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001771- Replaced most Unicode charmap codecs with new ones using the
1772 new Unicode translate string feature in the builtin charmap
1773 codec; the codecs were created from the mapping tables available
1774 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1775 encodings now include a mapping for the Apple logo)
1776
Tim Peterse3547fd2005-12-16 23:13:57 +00001777- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001778
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001779- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001780
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001781- A new AST parser implementation was completed. The abstract
1782 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001783 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001784
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001785- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001786 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1787
Neal Norwitz708e51a2005-10-03 04:48:15 +00001788- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1789
Neal Norwitz11bd1192005-10-03 00:54:56 +00001790- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1791 Provide a warning when a directory is passed on the command line.
1792
Neal Norwitz40d37812005-10-02 01:48:49 +00001793- Fix segfault with invalid coding.
1794
1795- SF bug #772896: unknown encoding results in MemoryError.
1796
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001797- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001798 supported a __len__() method which evaluated to False when the iterator
1799 was empty.
1800
Guido van Rossum630db602005-09-20 18:49:54 +00001801- On 64-bit platforms, when __len__() returns a value that cannot be
1802 represented as a C int, raise OverflowError.
1803
Skip Montanarof8948ca2005-09-19 03:54:46 +00001804- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001805 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001806
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001807- SF bug #893549: parsing keyword arguments was broken with a few format
1808 codes.
1809
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001810- Changes donated by Elemental Security to make it work on AIX 5.3
1811 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1812 bug #105470: test_pwd fails on 64bit system (Opteron).
1813
Guido van Rossum539c6622005-09-14 17:49:54 +00001814- Changes donated by Elemental Security to make it work on HP-UX 11 on
1815 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1816
Georg Brandl4550b8d2005-08-26 06:43:52 +00001817- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001818 (fixes bug #1119418).
1819
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001820- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1821
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001822- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1823 exceptions that cause a function to exit.
1824
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001825- The implementation of set() and frozenset() was revised to use its
1826 own internal data structure. Memory consumption is reduced by 1/3
1827 and there are modest speed-ups as well. The API is unchanged.
1828
Tim Petersde7990b2005-07-17 23:45:23 +00001829- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1830
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001831- SF bug #1229429: PyObject_CallMethod failed to decrement some
1832 reference counts in some error exit cases.
1833
Tim Petersecc6e6a2005-07-10 22:30:55 +00001834- SF bug #1185883: Python's small-object memory allocator took over
1835 a block managed by the platform C library whenever a realloc specified
1836 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001837 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001838 portable way to copy data from the C-managed block into Python's
1839 small-object space without risking a memory fault. Python's small-object
1840 realloc now leaves such blocks under the control of the platform C
1841 realloc.
1842
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001843- SF bug #1232517: An overflow error was not detected properly when
1844 attempting to convert a large float to an int in os.utime().
1845
Raymond Hettinger3296e692005-06-29 23:29:56 +00001846- SF bug #1224347: hex longs now print with lowercase letters just
1847 like their int counterparts.
1848
Michael W. Hudson188d4362005-06-20 16:52:57 +00001849- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1850 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1851 interpreter states; back out that fix and do a better job (see
1852 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1853 for a longer write-up of the problem).
1854
Michael W. Hudsondf888462005-06-03 14:41:55 +00001855- SF patch #1180995: marshal now uses a binary format by default when
1856 serializing floats.
1857
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001858- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1859 the routines that promise to produce IEEE 754 binary representations
1860 of floats now simply copy bytes around.
1861
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001862- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1863 278.
1864
Brett Cannonc3647ac2005-04-26 03:45:26 +00001865- patch #1109424: int, long, float, complex, and unicode now check for the
1866 proper magic slot for type conversions when subclassed. Previously the
1867 magic slot was ignored during conversion. Semantics now match the way
1868 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001869 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001870 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001871 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001872
Barry Warsawc8d907c2005-04-19 23:43:40 +00001873- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1874 NULL, now raise an AttributeError when attempting to set or delete the
1875 attribute. Previously a TypeError was raised, but this was inconsistent
1876 with the equivalent pure-Python implementation.
1877
Michael W. Hudson774479c2005-04-18 08:46:17 +00001878- It is now safe to call PyGILState_Release() before
1879 PyEval_InitThreads() (note that if there is reason to believe there
1880 are multiple threads around you still must call PyEval_InitThreads()
1881 before using the Python API; this fix is for extension modules that
1882 have no way of knowing if Python is multi-threaded yet).
1883
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001884- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1885 disabled caused a crash.
1886
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001887- Bug #1165306: instancemethod_new allowed the creation of a method
1888 with im_class == im_self == NULL, which caused a crash when called.
1889
Tim Petersecc6e6a2005-07-10 22:30:55 +00001890- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001891 fixes the crash seen in bug #1165761
1892
Raymond Hettinger96229b12005-03-11 06:49:40 +00001893- Added two new builtins, any() and all().
1894
Brett Cannon409d8f22005-03-05 06:47:57 +00001895- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001896 (e.g., ``class C(): pass`` is no longer a syntax error).
1897 Patch #1176012 added support to the 'parser' module and 'compiler' package
1898 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001899
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001900- Patch #1115086: Support PY_LONGLONG in structmember.
1901
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001902- Bug #1155938: new style classes did not check that __init__() was
1903 returning None.
1904
Tim Petersecc6e6a2005-07-10 22:30:55 +00001905- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001906 ('\') with a specific error message.
1907
Martin v. Löwisff232d72005-03-03 09:24:38 +00001908- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1909
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001910- Bug #1124295: the __name__ attribute of file objects was
1911 inadvertently made inaccessible in restricted mode.
1912
Tim Petersecc6e6a2005-07-10 22:30:55 +00001913- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001914 an ferror() call.
1915
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001916- min() and max() now support key= arguments with the same meaning as in
1917 list.sort().
1918
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001919- The peephole optimizer now performs simple constant folding in expressions:
1920 (2+3) --> (5).
1921
Raymond Hettingera422c342005-01-11 03:03:27 +00001922- set and frozenset objects can now be marshalled. SF #1098985.
1923
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001924- Bug #1077106: Poor argument checking could cause memory corruption
1925 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001926
Jeremy Hyltonab630502005-02-04 18:44:06 +00001927- The parser did not complain about future statements in illegal
1928 positions. It once again reports a syntax error if a future
1929 statement occurs after anything other than a doc string.
1930
Neil Schemenauercf52c072005-08-12 17:34:58 +00001931- Change the %s format specifier for str objects so that it returns a
1932 unicode instance if the argument is not an instance of basestring and
1933 calling __str__ on the argument returns a unicode instance.
1934
Tim Petersf4e69282006-02-27 17:15:31 +00001935- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1936 current thread state when the auto-GIL-state machinery knows about
1937 it (since the thread state is being deleted, continuing to remember it
1938 can't help, but can hurt if another thread happens to get created with
1939 the same thread id).
1940
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001941Extension Modules
1942-----------------
1943

Neal Norwitz10be10c2006-03-16 06:50:13 +00001957 util, whatsound, whrandom, zmod
1958
1959- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1960
1961- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001962 is deprecated. The undocumented re.engine variable no longer exists.
1963
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001964- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1965 SS2 (single-shift 2) escape sequences correctly.
1966
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001967- The unicodedata module was updated to the 4.1 version of the Unicode
1968 database. The 3.2 version is still available as unicodedata.db_3_2_0
1969 for applications that require this specific version (such as IDNA).
1970
Neal Norwitzb62c4332006-03-04 18:35:47 +00001971- The timing module is no longer built by default. It was deprecated
1972 in PEP 4 in Python 2.0 or earlier.
1973
Guido van Rossum1968ad32006-02-25 22:38:04 +00001974- Patch 1433928: Added a new type, defaultdict, to the collections module.
1975 This uses the new __missing__ hook behavior added to dict (see above).
1976
Georg Brandldbd83392006-02-20 09:42:33 +00001977- Bug #854823: socketmodule now builds on Sun platforms even when
1978 INET_ADDRSTRLEN is not defined.
1979
Georg Brandlf4f44152006-02-18 22:29:33 +00001980- Patch #1393157: os.startfile() now has an optional argument to specify
1981 a "command verb" to invoke on the file.
1982
Neal Norwitz082b2df2006-02-07 07:04:46 +00001983- Bug #876637, prevent stack corruption when socket descriptor
1984 is larger than FD_SETSIZE.
1985
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001986- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1987 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1988 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1991 than the system default domain.
1992
Martin v. Löwis14694662006-02-03 12:54:16 +00001993- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1994 are reported, the limit on path name lengths is removed, and stat reports
1995 WindowsError now (instead of OSError).
1996
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001997- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2072 the request code argument, which results in more C-like behaviour
2073 for large or negative values.
2074
Tim Petersecc6e6a2005-07-10 22:30:55 +00002075- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002131- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2132 been renamed to have only a single underscore prefix. This was done to
2133 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002134
Nick Coghlan43832302006-04-23 17:04:07 +00002135- PEP 338: new module runpy defines a run_module function to support
2136 executing modules which provide access to source code or a code object
2137 via the PEP 302 import mechanisms.
2138
Anthony Baxter93f5b932006-04-03 08:05:07 +00002139- The email module's parsedate_tz function now sets the daylight savings

2147 in attribute values.
2148
Anthony Baxterc51ee692006-04-01 00:57:31 +00002149- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002150 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002151 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002152 module will not be built.
2153
Tim Petersc17976e2006-04-01 00:26:53 +00002154- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2155 aren't officially supported here, and trying to use them will probably
2156 raise an exception some day. But dicts have been allowed, and "mostly
2157 worked", so support for them won't go away without warning.
2158
Georg Brandl338ef7d2006-03-31 18:42:16 +00002159- Bug #1445068: getpass.getpass() can now be given an explicit stream
2160 argument to specify where to write the prompt.
2161

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002170- Queue.Queue objects now support .task_done() and .join() methods
2171 to make it easier to monitor when daemon threads have completed
2172 processing all enqueued tasks. Patch #1455676.
2173

2177
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002178- email 4.0 package now integrated. This is largely the same as the email 3.0
2179 package that was included in Python 2.3, except that PEP 8 module names are
2180 now used (e.g. mail.message instead of email.Message). The MIME classes
2181 have been moved to a subpackage (e.g. email.mime.text instead of
2182 email.MIMEText). The old names are still supported for now. Several
2183 deprecated Message methods have been removed and lots of bugs have been
2184 fixed. More details can be found in the email package documentation.
2185
Walter Dörwald40108c92006-03-27 08:15:44 +00002186- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2187 (a subclass of tuple) that provides incremental decoders and encoders
2188 (a way to use stateful codecs without the stream API). Python functions
2189 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2190 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2191 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002192
Walter Dörwald067db482006-03-15 22:17:27 +00002193- Patch #1359365: Calling next() on a closed StringIO.String object raises
2194 a ValueError instead of a StopIteration now (like file and cString.String do).
2195 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2196 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002197
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002198- A regrtest option -w was added to re-run failed tests in verbose mode.

Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002209- PEP 343: new module contextlib.py defines decorator @contextmanager
2210 and helpful context managers nested() and closing().
2211
Martin v. Löwis415ed932006-02-27 19:56:30 +00002212- The compiler package now supports future imports after the module docstring.
2213

2216
Georg Brandlc98eeed2006-02-19 14:57:47 +00002217- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00002246 specifications, raises IOErrors when proxies for unsupported protocols
2247 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002270 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2271 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2272 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2273 Ronald L. Rivest offered this advice for Python:
2274
2275 "The consensus of researchers in this area (at least as
2276 expressed at the NIST Hash Function Workshop 10/31/05),
2277 is that SHA-256 is a good choice for the time being, but
2278 that research should continue, and other alternatives may
2279 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002280
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002281- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002327- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2328 ContentTooShortException, when the actually downloaded size does not
2329 match the Content-Length header.
2330

2334 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002335 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002336

2358 to W3C name (404 -> 'Not Found'). RFE #1216944.
2359
Georg Brandl9e43acf2005-07-04 17:16:07 +00002360- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2361 as this can cause problems with apps closing all file descriptors.

2374 Bug #1224621.
2375
Raymond Hettinger68c04532005-06-10 11:05:19 +00002376- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002377 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002378 the generate_tokens() function now accepts a callable argument that
2379 terminates by raising StopIteration.
2380
Georg Brandl9166e1a2005-06-04 09:20:03 +00002381- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2389 class at all.
2390
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002391- distutils.commands.upload was added to support uploading distribution
2392 files to PyPI.
2393
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002394- distutils.commands.register now encodes the data as UTF-8 before posting
2395 them to PyPI.
2396
Raymond Hettinger267b8682005-03-27 10:47:39 +00002397- decimal operator and comparison methods now return NotImplemented
2398 instead of raising a TypeError when interacting with other types. This
2399 allows other classes to implement __radd__ style methods and have them
2400 work as expected.
2401
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002402- Bug #1163325: Decimal infinities failed to hash. Attempting to
2403 hash a NaN raised an InvalidOperation instead of a TypeError.
2404
Tim Petersecc6e6a2005-07-10 22:30:55 +00002405- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2439
Guido van Rossumd0641422005-02-03 15:01:24 +00002440- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2441 disables recursive traversal through instance attributes, which can
2442 be exploited in various ways.
2443
Tim Peterse3547fd2005-12-16 23:13:57 +00002444- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002445 flags on the HTTP listening socket.
2446
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002447- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2448 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2449
Fred Drakefbdeaad2006-07-29 16:56:15 +00002450- Patches #893642, #1039083: add allow_none, encoding arguments to
2451 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002452
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002453- Bug #1110478: Revert os.environ.update to do putenv again.
2454
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002455- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2456
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002457- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2458
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002459- Enhancements to the csv module:
2460
2461 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002462 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002463 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002464 + Dialect parameter parsing has been re-implemented to improve error
2465 reporting.
2466 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2467 dictates.
2468 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002469 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002470 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002471 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2472 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002473 + reader now allows \r characters to be quoted (previously it only allowed
2474 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002475 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002476 + Dialect classes passed to the module are no longer instantiated by
2477 the module before being parsed (the former validation scheme required
2478 this, but the mechanism was unreliable).
2479 + The dialect registry now contains instances of the internal
2480 C-coded dialect type, rather than references to python objects.
2481 + the internal c-coded dialect type is now immutable.
2482 + register_dialect now accepts the same keyword dialect specifications
2483 as the reader and writer, allowing the user to register dialects
2484 without first creating a dialect class.
2485 + a configurable limit to the size of parsed fields has been added -
2486 previously, an unmatched quote character could result in the entire
2487 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002488 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002489 the parser field size limit (returning the former limit). The initial
2490 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002491 + A line_num attribute has been added to the reader object, which tracks
2492 the number of lines read from the source iterator. This is not
2493 the same as the number of records returned, as records can span
2494 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002495 + reader and writer objects were not being registered with the cyclic-GC.
2496 This has been fixed.
2497
Brett Cannone6539c42005-01-08 02:43:53 +00002498- _DummyThread objects in the threading module now delete self.__block that is
2499 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2500 lock primitives tend to be limited in number and thus should not be wasted on
2501 a _DummyThread object. Fixes bug #1089632.
2502
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002503- The imghdr module now detects Exif files.
2504
Raymond Hettinger6065d322004-12-20 23:51:53 +00002505- StringIO.truncate() now correctly adjusts the size attribute.
2506 (Bug #951915).
2507
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002508- locale.py now uses an updated locale alias table (built using
2509 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2510 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002511 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002512
Raymond Hettinger3557f422004-12-07 12:02:02 +00002513- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2514
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002515- the pickle module no longer accepts the deprecated None option in the
2516 args tuple returned by __reduce__().
2517
Brett Cannon84667c02004-12-07 03:25:18 +00002518- optparse now optionally imports gettext. This allows its use in setup.py.
2519
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002520- the pickle module no longer uses the deprecated bin parameter.
2521
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002522- the shelve module no longer uses the deprecated binary parameter.
2523
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002524- the pstats module no longer uses the deprecated ignore() method.
2525
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002526- the filecmp module no longer uses the deprecated use_statcache argument.
2527
Raymond Hettinger664347b2004-12-04 21:21:53 +00002528- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2529 extended or overridden by subclasses. Formerly, the subclassed method would
2530 be ignored by the rest of the module. (Bug #1078905).
2531
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002532- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002533 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002534
Walter Dörwald36733692004-12-22 12:50:50 +00002535- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2536 once when a size argument is given. This prevents a buffer overflow in the
2537 tokenizer with very long source lines.
2538
Barry Warsaw538561e2006-01-01 21:48:54 +00002539- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2540 immediately after creating the object, without any intervening
2541 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002542
Skip Montanaro05885812005-01-16 20:48:27 +00002543- The reconvert.quote function can now emit triple-quoted strings. The
2544 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002545
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002546- ``UserString.MutableString`` now supports negative indices in
2547 ``__setitem__`` and ``__delitem__``
2548
Greg Ward40407942005-03-05 02:53:17 +00002549- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2550 correctly.
2551
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002552- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2553 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2554 character even if the user has passed a size parameter to get a proper
2555 line ending. Remove the special handling of a "\r\n" that has been split
2556 between two lines.
2557
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002558- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2559 about illegal code points. The codec now supports PEP 293 style error
2560 handlers.
2561
Walter Dörwald78a78b02005-09-01 12:04:29 +00002562- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002563 from the input stream, so that the output is a byte string in the correct
2564 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002566- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2567 considering it exactly like a '*'.
2568
Walter Dörwald007f8df2005-10-09 19:42:27 +00002569- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2570 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002571
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002572- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2573
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002574- Patch #1413711: Certain patterns of differences were making difflib
2575 touch the recursion limit.
2576
Walter Dörwald58917a62006-03-31 15:26:22 +00002577- Bug #947906: An object oriented interface has been added to the calendar
2578 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002579 called as a script (e.g. via ``python -mcalendar``). Localized month and
2580 weekday names can be ouput (even if an exotic encoding is used) using
2581 special classes that use unicode.

2590
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002591- Build support for Win64-AMD64 was added.
2592
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002593- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2594
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002595- Patch #881820: look for openpty and forkpty also in libbsd.
2596
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002597- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2598 The zlib module is now builtin on Windows.
2599
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002600- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2601
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002602- Bug #1189330: configure did not correctly determine the necessary
2603 value of LINKCC if python was built with GCC 4.0.
2604
Trent Mick8321b422005-07-26 02:29:21 +00002605- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2606 vulnerability in zlib 1.2.1 and 1.2.2.
2607
Brett Cannon08cd5982005-04-24 22:26:38 +00002608- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2609 flags that change binary compatibility. Changes were also made to
2610 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002611 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002612
Bob Ippolitoed233462005-03-29 13:47:59 +00002613- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2614 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2615 no longer exists). This configure patch makes things right.
2616
Martin v. Löwise2713be2005-03-08 15:03:08 +00002617- Bug #1158607: Build with --disable-unicode again.
2618
Brett Cannon46d96232005-02-16 00:07:19 +00002619- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2620 defined. Discovered as a result of not being able to build on OS X.
2621
Brett Cannon516592f2004-12-07 00:42:59 +00002622- setup.py now uses the directories specified in LDFLAGS using the -L option
2623 and in CPPFLAGS using the -I option for adding library and include
2624 directories, respectively, for compiling extension modules against. This has
2625 led to the core being compiled using the values in CPPFLAGS. It also removes
2626 the need for the special-casing of both DarwinPorts and Fink for darwin since
2627 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2628 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2629 Fink, ``-I/opt/local/include`` for DarwinPorts).
2630
Brett Cannon43802422005-02-10 20:48:03 +00002631- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2632 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2633 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2634 Closes bug #1096244. Thanks Gregory Bond.

2637-----
2638
Tim Petersc9d78aa2006-03-26 23:27:58 +00002639- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2640 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2641 is obtained via the ``PyObject_`` family, it must be released via the
2642 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2643 always been officially true, but when Python's small-object allocator was
2644 introduced, an attempt was made to cater to a few extension modules
2645 discovered at the time that obtained memory via ``PyObject_New`` but
2646 released it via ``PyMem_DEL``. It's years later, and if such code still
2647 exists it will fail now (probably with segfaults, but calling wrong
2648 low-level memory management functions can yield many symptoms).
2649
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002650- Added a C API for set and frozenset objects.
2651

2653
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002654- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2655 mapping argument now. This string is used as a mapping table. Byte values
2656 greater than the length of the string and 0xFFFE are treated as undefined
2657 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002664
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002665- Patch #1276356: New resource "urlfetch" is implemented. This enables
2666 even impatient people to run tests that require remote files.
